Prydz, Espen BeerJolliffe, Dean2016-04-262016-04-262016-03https://hdl.handle.net/10986/24148World Bank's international poverty line of $1.90/day, at 2011 purchasing power parity, is based on a collection of national poverty lines, which were originally used to set the international poverty line of $1.25/day at 2005 purchasing power parity. This paper proposes an approach for estimating a more recent, complete, and comparable collection of national poverty thresholds from reported national poverty rates. The paper presents a set of international poverty lines based on this new database of national poverty lines. In contrast to the lines used to estimate the $1.90 international poverty line, this approach produces national poverty lines that are (1) consistent with national poverty rates, (2) expressed in common units, and (3) provide greater support to the estimated international poverty line. These national poverty lines are used to estimate an extreme international poverty line, and three higher lines that are more relevant for higher-income countries. A key finding provides evidence of the robustness and relevance of the $1.90 international poverty line as a measure of extreme poverty for low-income countries.en-USCC BY 3.0 IGOREGIONAL POVERTY LINESPOVERTY THRESHOLDPER CAPITA CONSUMPTIONLIVING STANDARDSHEADCOUNT RATIOINCOME DATARURAL POVERTY LINEDEVELOPMENT RESEARCHPOVERTY LINESCONSUMPTION EXPENDITURESHOUSEHOLD SURVEYSOCIAL NORMSCONSUMPTIONCAPITA INCOMEPOVERTY LINEHUMAN ENERGYECONOMIC GROWTHNATIONAL ACCOUNTSDEVELOPMENT REPORTFOOD POVERTYPOVERTY MEASUREMENTMEAN VALUEINCOME POVERTYINCOMEPOVERTY RATESPOVERTY ESTIMATESNATIONAL POVERTY LINEINCOME DISTRIBUTIONSPOOR COUNTRIESDEVELOPING WORLDDENSITY FUNCTIONMEASUREMENT OF POVERTYDEVELOPING COUNTRIESCONSUMPTION MEASUREHEALTH INSURANCERURAL POVERTYINCOME DISTRIBUTIONABSOLUTE POVERTYNATIONAL POVERTYPOOR PEOPLERURALLOG-LOG MODELHOUSEHOLD_SURVEYNATIONAL POVERTY RATECONSUMPTION AGGREGATEINTERNATIONAL POVERTY LINESDEVELOPMENT GOALSGLOBAL POVERTYECONOMICSMEASURESPOVERTY MEASURESNATIONAL POVERTY LINESFIXED EFFECTSREGIONINSURANCEPOVERTY REDUCTIONECONOMIC DEVELOPMENTRICH COUNTRIESPUBLIC POLICYSTANDARD DEVIATIONREGIONAL POVERTYABSOLUTE VALUEPER CAPITA INCOMEEXTREME POVERTYDEVELOPMENT ECONOMICSPOVERTYNATIONAL POVERTY HEADCOUNTLOW-INCOME COUNTRIESPOLITICAL CONSTRAINTSEXCHANGE RATESHOUSEHOLD CONSUMPTIONTRANSFERSPOVERTY UPDATECONSUMER PRICE INDEXINTERNATIONAL POVERTY LINEPOVERTY HEADCOUNT RATESPOLICY RESEARCHPOVERTY STATUSPOVERTY RATEPOORDATA ISSUESPOVERTY ASSESSMENTCONSUMPTION EXPENDITUREHOUSEHOLD SURVEYSWELFARE MEASUREMICRO DATAPOVERTY ASSESSMENTSPOVERTY HEADCOUNT RATEDEVELOPMENT INDICATORSSIGNIFICANT CORRELATIONDEVELOPMENT POLICYFOOD ITEMSINEQUALITYGROWTHWorking PaperWorld Bank10.1596/1813-9450-7606
